6 Claims.

My invention relates to that class of devices which are designed to holda plurality of loose leaves and which may, if desired, be filled up fromtime to time. It is well known that ring books of this type even ifequipped with a. oneinch diameter ring will hold only approximatelyone-half inch of sheets. Moreover, if you desire to insert or remove asheet from the center portion of the bound sheets, it is an extremelydiflicult job because of the fact that you have to swing part of thesheets over on one half of the rings and the other portion remains onthe remaining half and if you do not wish to divide or make your insertexactly in the center it is necessary to remove a number of. sheets andreplace them all of which is timewasting and uneconomical.

My invention has for its object to provide means for binding a number ofloose leaves in a book in which the binder will hold its full capacityand in which it is possible to gain access to a leaf or to insert a leafat any part of the volume without the slightest difiiculty.

My means of accomplishing the foregoing objects may be more readilyunderstood by having reference to the accompanying drawings which arehereunto annexed and form a part hereof, in which Fig. .1 is aniosometric perspective view of a fragmentary portion of a binder with myattachment, the parts being shown in separate position for the sake ofclearness;

Fig. 2 is a top or plan view of the binder with the parts in assembledposition;

Fig. 3 is an end .view of the same;

Fig. 4 is a plan view of the device with the impaling pins separatedfrom the metal back;

Fig. 5 is an end view of the same; and

Fig. Sis a section taken on the line 6-6 in Fig. 4.

Similar reference numerals refer to similar parts throughout the entiredescription.

As shownin the drawings, the binder is attached to a pair of covers Iand 2. It comprises a metal back 3, one edge 4 of which is bent at rightangles thereto so that the metal back in cross section presents theappearance of an L.

A hinge 5 is provided on the other edge of the metal back and a hingedbar 6 is secured thereto by means of a hinge pin 1 in the usual manner.This hinged bar 6 is provided with a plurality of impaling pins 8 andhas a number of "perforations 9 formed intermediate the impaling pins.As shown the pins are three in numher though it will be obvious they canbe any number desired. The ends I of the hinged bar are bent upwardlyfor the purpose of forming. a spring lock which will be hereinafter ex-"plained. The pins 8 are arcuate but ona very large radius so as to bealmost straight and terminate in points which are adapted to enter butnot pass through apertures ll formed in a" detachable bar 12 which alsocarries impaling pins l3 which areadapted to enter the apertures 9formed in the hinged bar 6;

The detachable bar 12 is preferably formed of spring steel and hasmounted adjacent its ends.

two locking pins l4 and I5. These pins are adapted to register withapertures 16 and I1 formed in the narrower portion 4 of the L shapedmetal back 3. Notohes l9 are cut in the ends of the detachable bar I2and thesenotches are engaged by the upper ends 18 as clearly seen inFigs. 3 and 5. The operation of the device is as follows: 1

The loose leaves (not shown) are provided with perforations adapted toregister with the impaling pins and are placed upon the pins 8. The pinsl3 are then inserted in the intermediate perforations and as thepointson these pins are smaller than the apertures 8 so that only the pointsof the pins can enter the apertures the pins cannot pass through them,The hinged bar 6 is then swung over until it reaches the position shownin Fig. 3 when the detachable bar will pass beneath the portion 4 of theL shaped metal back 3 and the pins I4 and I5 will be brought intoregister with apertures l6 and Il. Due to the resiliency of the metal,out of which the detachable bar I2 is formed, pins l4 and [5 will atonce enter theholes and the ends N3 of the upwardly bent portions In ofthe hinged bar will engage the notches IS in the detachable bar l2 andserve as a spring lock for holding the bar 12 firmly in place and willalso prevent the bar I! from sliding forward. It will be obvious fromthe foregoing description of the pins 8, since they extend the entirewidth of the volume, that any desired number of leaves can be leftimpaled upon them when the detachable bar is removed for the purpose ofgaining access to any leaf without the slightest difiiculty regardlessof its location.

It will also be clearly apparent that the space between the hinged barand the detachable bar can be completely filled with loose leaves.

To remove the leaves the ends of the detachable bar are presseddownwardly until the pins l4 and [5 are disengaged from the apertures 16and Il when the volume can be swung upon the hinge 5 and as soon as thedetachable bar is in the position shown in Fig. 5 it can be lifted upwith as many leaves as desired leaving the remainder on the pins 8 or itcan be lifted entirely off of the leaves and all the leaves in thevolume will be left on the pins 8.

By making the impaling pins slightly arcuate in form I facilitate thefiat opening of the book.

It will be apparent from the foregoing that I have provided a structurewhich entirely overcomes the objectionable features pointed out in thering binders used in this class of work and have attained the result bymeans of a very simple and economical form of structure.

It may well be in practice that some other form of locking thedetachable bar to the metal back will be found and although I have shownand described the specific type of structure for this purpose, I wish tobe understood that these illustrations are solely for the purpose ofshowing a preferred embodiment of the invention and not with anyintention of being limited to the specific structure shown and describedexcept as such limitations may appear in the hereinafter appendedclaims.

Having described my invention what I regard as new and desire to secureby Letters Patent is:
